Letters Patent No. 109,353, dated November 15, 1870.

V IMPROVEMENT IN DRAFT DEVICES FOR HARVESTERS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, J OHN M. SMITJJ, of Jerseyville,

, in the county of Jersey and State of Illinois, have .in-

vented a new, useful, and improved Draft Device for Reapers; and I dohereby declare that the following is a full and exact description of thesame, reference being had to the accompanying drawing and to thelettcrsof reference marked thereon.

This invention consists of a bar of peculiar con-' strnction, which isemployed, in connection with the frame of a reaper and the ordinarytripletree, for the purpose of permitting the attachment of three horsesdirectly to the reaper in the place 'of four hitched in pairs, asusually employed.

In the drawing- I Figure 1 represents a plan view of m y invention, and

Figure 2, a side elevation of the same.

To enable others skilled in the art to make and use my invention, I willnow proceed to describe fully its construction and method of operation.A represents the draft-pole.

B B, the front part of a McCormick reaper-frame.

0, an ordinary tripletree.

I) represents an iron bar, which is secured to arms B-B' by bolts orscrews, or other convenient fastening. The right end of this bar is bentin clevis-shape, to form a guide for the chain, and is provided withrollers, as shown. i

E represents the draft-chain, which is attached to the tripletree and toany convenient part of the frame. The bar D, it will be observed, isfurnished with a series of holes, by means of which it may be adjustedlaterally upon the frame, for the purpose of bringing the horses intoany desired position.

The advantages of employing three horses abreast, in place of four, inpairs, are evident. The draft is more equally distributed between them,and they are moreperfcctly under the drivers control. It is believedthat an equal or nearly equal amount of work can bc aecomplished bymeans of this device as is accomplished by the old method, although oneless animal is employed. By connecting the draft to the frame of themachine instead of to the pole, the point of attachment may be varied tosuit the necessities of the case.

Having thus fully described myinvention,

What I claim as new, and desire to secure b Letters Patent of the UnitedStates, is-- The adjustable bar D, constructed specifically asdescribed, With its rollers, in combination with.frame, chain, andtripletree, as and for the purpose described.

This specification signed and witnessed this 29th day of August, 1870.

JOHN M. SMITH.
